Lots of this is in Potlatch:

- 'whichways': return IDs of all ways within a bounding box
- 'getway': return one way as an ordered list of lats and longs (and  
some other stuff)
- 'putway': save a getway-formatted way back onto the server
- 'deleteway': delete a way (and all constituent nodes and segments,  
unless they're used elsewhere)

Have a look at the rubyamf.cgi source (or PHP equivalent) and you  
might find some stuff you can borrow/reuse.
