This is a one-time cost, which is (nearly) over. Virtually *all*
of the problems were caused by severe limitations or fundamental
design flaws in svn, to boot -- a strong argument for getting *away*

This is a valid point that I cannot address. If you are truly happy
with svn, switching to a new system is an effort which basically
cannot be mitigated.

This is somewhat unfortunate. However, it isn't as bad as it looks at
first blush. There are a number of ways to communicate monotone
revisions without using 20-character hex strings:
* Shorter hex strings: monotone will expand unique prefixes to the
full revision. In most cases, you can use, say, '2d62a' instead of
* Selectors; revisions can be named by a rich set of selectors over
certs on the revision and other properties; for example,
h:im.pidgin.pidgin is the head revision of im.pidgin.pidgin.
A more complicated selector, a:elb at pidgin.im/d:2007-01, matches all
revisions committed by me in January of 2007. See
http://venge.net/monotone/docs/Selectors.html for more information.
> * Having to maintain two revision control systems (mtn and svn)
We shouldn't have to do this. There are just a few more branches and
things to be moved over to monotone, after which we can tar the svn
history up someplace and consult it only if someone things they have
found a problem.

This is a real problem for which I do not have an answer. It is being
worked on by the monotone folks.

That is trac, not monotone. Svn on trac will look substantially
similar to mtn on trac. There is a viewmtn, which may or may not be
closer to something you like. We can install it on pidgin.im and give
it a spin.

This is quite possible, I don't know. If meld knows something
specific about svn, it may have capabilities there which it doesn't
have with mtn. If this is something important and useful (I don't
know, I've never used meld in any such way), we can look into getting
some equivalent functionality supported in monotone. If meld uses the
pristine copy in .svn, it will be a bit more work -- but obviously,
all the information is still there.
In short, I think we can address at least some of these issues, either
immediately or in the near future. Some are more difficult (or
impossible) to address. In the meantime, the more we know about
sticking points, the easier it will be to fix them; please let me know
what problems you encounter.
 Some tags are yet to be imported. The *hard* part is over.
The laws that forbid the carrying of arms are laws [that have no remedy
for evils]. They disarm only those who are neither inclined nor
determined to commit crimes.
