I have not looked much into XSP. I'll have a look.
What I was planing on doing is a mod_mono for allowing server extentions
written with mono. The rest of ASP.NET was designed to be in a class lib
and not to depend on a webserver, so that project can be seperate from
mod_mono. mod_mono can be shared between an ASP.NET implementation, and an
XSP implementation. Another thing that might help to get XSP on mono would
be to create a java compiler like Microsoft is doing with their new
j++.net project. Create a java class lib that wrap the .net ones. It then
would be posible to compile java programs for use with mono without code
changes.
