Flash 8-9 FTP reconnect capability?

Hi
I have some clients who want to upload 2+ Gig files within a Flash interface
These kinds of files can take 1/2 day to upload…
And sometimes, connections take a nose dive.

With this as a reality, does Flash 8-9 have advanced FTP features such as reconnect ?
And, can Flash 8-9 do SFTP ?

It’s ok if something like MProjector or SWFKit is required.

many thanks
