Description (last modified by )
The OSM server will whine if I request a bbox bigger than 0.25. It would be nice if JOSM could optionally take the action of dividing the selected download areas into smaller areas when this is the case & automatically download and merge them.
The GPX "download are around track" feature may be of interest as related already existing functionality.

When we have opportunistic locking with API 0.6 though, it would be a good idea though to add support for read-only download servers so that you can choose to download from a mirror and not from the main server, which will then allow requesting larger areas.
I'll re-open the ticket so that we have a reminder of that. It would require splitting the configuration to allow any number of download servers and only one upload server.

I'm not familiar with the internals of JOSM, but this sounds like a really good idea, especially when it comes to reducing load on the main api server. I think it would be a good idea to have xapi mirrors in Europe, US, and Asia, then JOSM and Potlatch could do all their downloading from these read-only servers, thereby reducing load for the upload api server, and downloading could be sped up simply by adding another mirror server. Add on geolocating dns balancing, and editor software could download from xapi.openstreetmap.org, which would redirect to a local server automatically. It'll be a while before OSMF gets around to something like this though.
In the mean time, is there any way to set up downloads from a different server than uploads in JOSM, such as what's mentioned above?

The new "mirrored download" plugin allows it: http://wiki.openstreetmap.org/wiki/JOSM/Plugins/mirrored_download
The reason for restricting downloads of large data sets from server is to reduce server load. JOSM will not work against the interests of the server maintainers.
