Interesting, meeting really helped,

Yesterday, discussion with Chris Wilson and Adrian Bateman, of MSIE  
team, revealed that allowing arbitrary flavours would be a big  
security hole for Windows at least (I believe this is Windows only but  
can't confirm yet).

So it seems the list of safe encodings is something that would need to  
be worked out.
A safer approach may be to require that the browsers make sure the  
things sipped into the clipboard/drag-content are only safe things.

Safe things include html without scripts, all picture formats  
(postscript as well?)  and most media, but not html with scripts, not  
windows metafiles, not OLE or MS-office documents.

Adrian indicated method to convert html to safe-html seem to be there  
in MSIE 8 already. Sanitization is probably the right term here.
