Very good to hear.

Hmm... the file upload tag is on my list of things to do some time but 
we haven't got to it yet - so that's why it doesn't work :)

What would you want the behaviour to be?  Should it dump the data to a 
temporary file somewhere and give you the filename?  Should it return a 
stream object with data in it that you could write to a file?  I'm 
assuming the former might be better since you don't know how big the 
file might be and probably don't want to keep it all in memory.

I'll try and get to this today or over the weekend.  If you wanted to 
poke more you'd need to look at implementing a subclass of IAInput to 
handle 'file' types... but then Seaside does currently get multipart 
data from the webservers and I haven't even looked how that should work 
yet...  the key parts are going to be IAKom and IARequest.
