I managed to get it working using file://.  Haven't tried svn+ssh yet  
but I've had persistent problems getting ssh to work properly on my  
macbook; not sure why yet but I haven't had time to play around with it.

That hasn't been decided yet and will be up to a consensus of the  
core devs, but I think the odds are in favor of allowing https:// but  
against allowing http://.

As for setup that could be anyone with admin privs, though it may be  
best left up to Chris D, Jason, or Mauricio.

Probably again a consensus issue, but you can choose one route.  My  
inclination is the former if it's easier.

Not sure.  I've never used one personally, but (as Jason suggests) if  
you have ideas for one you can propose them, or we can suggest devs  
set up svn::ignore locally.

Seems fine, though a simple 'svn file:///home/hartzell/bioperl'  
checkout gets everything (all distros, branches, etc).  We need to  
make sure everyone uses 'svn co file:///home/hartzell/bioperl/bioperl- 
live/trunk /live' or similar if they just want the latest core/db/etc.

We'll also need to start a svn wiki page to show how to get relevant  
distros (similar in style probably to the cvs page, with dev  
information, how to set up ssh keys, https stuff, etc).

I think a clean cut-over.  Everyone would be warned to hold commits  
for a day (lest they be lost), then probably do something in this order:

- switch cvs to read-only except for svn commits
- run a clean cvs2svn
- set up svn as read/write
- set up test commits to cvs via svn
- disable cvs commit messages to bioperl-guts, enable svn commit  
messages in it's place.
- push svn commits over to read-only cvs

cvs >>must<< be read-only after that point (no cvs->svn commits),  
with write access only available through svn.  If at some future  
point there is no reason to keep it around or that it is more trouble  
than it's worth, we can make a decision then on cvs's fate.
