paypal SOAP API from ZSI or SOAPpy?

[Chris Curvey]

Anyone had any luck with this? (Or can anyone just warn me off it
right now?)

I'm trying to just set up the service proxy via WSDL, and I'm getting
either a runaway process that's chewing up tons of memory or a very
quick stack trace.

I've tried both ZSI and SOAPpy (both stable and release candidate
versions)
