IMO 1.0 - or at least it's more widely tested.

Not that I know of.

Also none that I know of.

Unsure on that one.  It could easily be, as parts where I had tried to 
consider CPU cache efficiency have been ripped apart and extra code has been 
added into parts which I expect would be performance critical, but I haven't 
done any profiling to back this up.  1.0 does all I want it to so I've had
no need to test 1.1.1 or consider submitting any code for a post-1.0 release
(be it based on 1.1.1 or 1.0).  I don't know what the other developers are
up to either, probably happily using 1.0 too :-)

> 5) any other caveats?

If you use 1.0 and find a real bug I will probably try to find/fix it.
Under 1.1.1 I'm less likely to but the person who did the code for 1.1.1
might.

I did a lot of work leading up to 1.0 making sure it was fully tested
and reliable.  I am aware of only two problems - given a network which
does not generate its own problems such as out of order packets; one is
that sometimes some pppds are left around (not really a pptp bug) and
the other is that with Win2000 it reports that real ACCMs have been sent
but it does nothing with the ACCMs.  1.1.1 doesn't address either of
there issues though - it was a first cut toward supporting something
which I am convinced is not worth supporting (the broken and fundamentally 
flawed congestion control protocol from Microsoft).
