Just FYI, we're working on both (crosswiki-upload and 1-click crosswiki file move), but we're not quite there yet.
As mentioned on commons list a cross site upload tool is in early / alpha / experimental testing: http://lists.wikimedia.org/pipermail/commons-l/2010-March/005335.html
To summarize from that post you can visit: http://en.wikipedia.org/w/index.php?title=Wikipedia:Sandbox&action=edit&...
Clicking on the insert image icon, then the upload button, then wait a few seconds ... if the iframe proxy is working you should see your recent uploads to commons. Then click "upload to commons" and more waiting then you can should be able to upload to commons from en.wikipedia, once done uploading it prompts you to insert your uploaded asset into the article.
Its still kind of early on in development so don't be too surprised if it does not work. But let me know if you run into issues, and I can try and iron them out. ( with the exception being IE that for session iframes which needs special p3p headers and or user invoked reduced privacy settings to work the same as the other browsers. )
