\subsection{Controller library}
\tmp{release a general-purpose controller library}
We've done lots of design and development on our controller interface, which
allows UI applications and other tools to interact with Tor. We could
encorage the development of more such tools by releasing a {\bf
general-purpose controller library}, ideally with API support for several
popular programming languages.
\section{User experience}
\subsection{Get blocked less, get blocked less hard}
\tmp{Implement and publicize blind-signature based credential scheme}
Right now, some services block access to Tor because they don't have a better
way to keep vandals from abusing them than blocking IP addresses associated
with vandalism. Our approach so far has been to educate them about better
solutions that currently exist, but we should also {\bf create better
solutions for limiting vandalism by anonymous users} like credential and
blind-signature based implementations, and encourage their use.
\tmp{Maybe make a minimal RBL thing}
Those who do block Tor users also block overbroadly, sometimes blacklisting
operators of Tor servers that do not permit exit to their services. We could
obviate innocent reasons for doing so by designing a {\bf narrowly-targeted Tor
RBL service} so that those who wanted to overblock Tor clould no longer
plead incompetence.

\subsection{Firewall-level deployment}
\tmp{Make our new TransPort logic more portable and tested}
Another useful deployment mode for some users is using {\bf Tor in a firewall
configuration}, and directing all their traffic through Tor. This can be a
little tricky to set up currently, but it's an effective way to make sure no
traffic leaves the host un-anonymized. To achieve this, we need to {\bf
improve and port our new TransPort} feature which allows Tor to be used
without SOCKS support; to {\bf add an anonymizing DNS proxy} feature to Tor;
and to {\bf construct a recommended set of firewall configurations} to redirect
traffic to Tor.
\tmp{Write logic for Tor to act as a DNS server}
\tmp{Write necessary glue code, scripts, and docs so users who want to use

This is an area where {\bf deployment via a livecd}, or an installation

\subsection{Unified documentation scheme}
\tmp{Keep track of all the docs we've got}
We need to {\bf inventory our documentation.} Our documentation so far has
been mostly produced on an {\it ad hoc} basis, in response to particular
needs and requests. We should figure out what documentation we have, whih of
it (if any) should get priotority, and whether we can't put it all into a
single format.

\subsection{Missing technical documentation}
\tmp{Revised design paper, or design paper plus errata}
\tmp{``How to play nice with Tor''}
We should {\bf revise our design paper} to reflect the new decisions and
research we've made since it was published in 2004. This will help other
researchers evaluate and suggest improvements to Tor's current design.
Other projects sometimes implement the client side of our prototocol. We
encourage this, but we should write {\bf a document about how to avoid
excessive resource use}, so we don't need to worry that they will do so
without regard to the effect of their choices on server resources.
