We got a little stuck with the Apache-style license because it is too
open, and it seemed from the discussions that there are a few people
waiting to make commercial versions of TSVN. Apache would allow them to
make it closed source and would not require proper attribution to Stefan
(maybe in the source, but not user-visible).

It's not clear exactly why he objected. It may be for because the Apache
license we were proposing at that time is not a copy-left license, so
someone could make a closed source commercial application from it. A
different copy-left license might satisfy him.

I thought we decided that was not the case. You mentioned Scintilla at
one stage, but that is not GPL. Neon is LGPL, so that is OK to include.

Stefan suggested the Artistic license, which is better than most for
requiring attribution and in the case of commercialisation a copy of (or
link to) the original open source version. According to GNU and OSF it
is not a well written license and has too many legal loopholes and
ambiguities. There is a version 2 on the way, but I don't know when.

I suggested the Mozilla public license or Sun's CDDL variant of it.
Stefan felt those were 2 much legalese, and also too US-specific.

So the answer is that it's still a possibility, but the discussion
stalled and we moved onto other things. If you have any
suggestions/recommendations we'd be glad to hear them.

Simon
