Spyne supports Point, Line, Polygon and their Multi* variants. e.g.:

This means it can validate WKT input and produce WKT output.

It also includes SQLAlchemy adapters for these types. This means you
don't need to use  GeoAlchemy if you have Spyne.

Finally, Spyne can return your data in Soap, Xml, Json, Yaml, MsgPack,
html table, html microformat, etc. etc. or you can implement your
protocols if you don't like the ones already provided.

If you have further questions you can use Spyne tag in stackoverflow or

Disclaimer: I'm the author of Spyne. I already have GIS projects based
on Spyne in production.
