Allowing partial ways in the editors for the current bbox. I think hacking and breaking ways is bad, duplicate information, missing tags upon edit etc. I thinkAny comments?storing ways with their tags per 'new segment' is bad too; hence the reason I proposed to use an ordered relation to represent ways.With 40k nodes in a way it takes the API about 30 seconds just to generate and serve the XML for the way, /without/ the nodes.The .osm file with no node data goes upto about 100kb. (With node datathat's 5-6MB)To make a modification to the way, ie: add a tag, you have to reupload that 100kb of XML, and sit back, probably make a cup of coffee to passthe time.Fix the API. (and the implementation if it takes you that long ;)
Actually this isn't just an implementation problem, it is also a social limit. If 12 people were to request large highly detailed areas (and they were on a slow network connection), then you suddenly have everyone else locked out from doing bulkapi requests, until they have cleared.
There are other better ways to get large amounts of data, such as mirror API servers or the planet file. With the exposure of the node/ way/relation version numbers in API 0.6 this will make it much easier to deal with mirrored api servers.
