I'm going to rephrase the introduction. I'll probably have to keep it
very simple (no details about specific platforms) and then add the fine
print about what works and what doesn't elsewhere.

That depends on how capable the builtin server is. In principle it
should work. On the PC you would have to install obexd >= 0.19 with its
SyncEvolution plugin enabled, so that connection requests from the N900
get forwarded to SyncEvolution.

The web site documents the stable release, 0.9.2, which doesn't have a
server mode. 1.0 beta introduces that, but the web site hasn't been
updated yet. Partly because of lack of time, partly because it is still
a bit experimental.

No, because 0.9.x doesn't support Bluetooth.

Yes.

It would be preferable because both sides are open source and can (and
will) be fixed if problems are found. There may also be technical
advantages. The Synthesis engine used by SyncEvolution is the best
implementation of SyncML that I have come across so far.
