The big question is how web2py will evolve with regard to plugin/ appliance architecture, because that would determine how to go about adding geo stuff in a systematic manner. I'm not sure I'd like it as a t2-style addon, but then again adding it to the core would mean way too many dependencies and try/catching.
A quick glance how I could imagine geo func in web2py (this is just me thinking out loud, I'm aware of sahana and other projects and do not mean to impose these ideas on them): MODEL - the DAL would need to be extended with geometry types (I know Massimo is not too keen on this one :), which would allow for some operator magic web2py is known for. So you could do something like db(GEOM_POINT(5,5) in db.table.polygon_column).select() db(db.table.polygon.length > 100).select (orderby=~db.table.polygon.area) also, some geo-specific velidators could be useful (IS_CONTAINED, IS_IN_RANGE, etc). VIEW - It would be nice to have a generic helper which we could interface to popular web mapping tools. Think layer1=LAYER(backend='googlemaps', name.., params....)
