Of course there are problems with trying to do this.
But if you're always afraid of running into pitfalls you'll never
get anything done. I know you are particularly keen on pointing
out pitfalls because you're somebody who often ends up having to
work around them professionally, and I sense some love-hate
relationship going on here :)
We had some very interesting discussions with the Tmate folks
when they first announced SubGit at Subversion Day last year:
http://www.elegosoft.com/en/company/news/news-in-detail.html?tx_ttnews[pointer]=1&tx_ttnews[tt_news]=114&tx_ttnews[backPid]=195&cHash=f876117be36ef5742b4977d7be07b5da
The announcement sparked some interest in German media:
http://www.heise.de/developer/meldung/Transparenter-Abgleich-zwischen-Subversion-und-Git-1246894.html
My own conviction is that their entire endeavor of rewriting
Subversion and related components in Java is outright crazy.
But I'm not a Java developer, so maybe I just don't get it.
And the quality that Tmate produces is astounding, and the
persistence they show with keeping up with Subversion's
feature set in SVNKit is highly commendable.
Generally, the problem they're tackling with SubGit is a giant
compatibility mapping problem between two very different data
structures. It is quite interesting to see how much of that
problem space they can actually solve, and also how long it has
taken them to solve it! One of the developers at Tmate even
made this problem part of his thesis.
So please, before you dismiss these efforts by pointing out
the first minor potential compatibility problem that comes to mind,
pay them some respect for their efforts -- they've certainly
done their homework around keyword expansion, and lots more.
