Forum OpenACS Q&A: Response to Anyone got a SOAP solution they are happy with?

I was about to put the finishing touches on a project proposal that would use AOLServer (but not OpenACS) along with TclSOAP, and then I discovered this thread.

My client claims that they need very high performance, although I'm skeptical of their need for such performance.  I sorta figured that I would simply do an ns_register_proc with procs I write with TclSOAP, and that things would work just fine.

Am I crazy for trying this approach?  Should I try nssoap instead?  I just checked out the latest nssoap sources, and they look reasonable, even if they haven't been touched in a few months.  Should I be wary?

I was convinced that this would be a pretty simple project, but previous comments in this thread are getting me increasingly worried.
