FTP transport alternatives for faster throughput

[DevNull43 <de...@gmail.com>]

I've been wondering so many times about FTP alternatives for faster
transfers.

I've seen commercial companies with nice experimental protocols boosting
throughput efficiency ( but haven't had the chance to test myselves).

http://www.dataexpedition.com/
http://www.filecatalyst.com/ 
http://www.asperasoft.com/en/technology/fasp_overview_1/fasp_technology_overview_1 
http://www.rocketstream.com/home/default.aspx 

The performance is so promising that I wonder how is possible it's not
widely used.

My only guess is they are not standards, not OpenSource, and are
copyrighted.

I wonder how FTP protocol has not been enhanced in such a way in the
standard.

Do you know of any OpenSource transfer protocol similar to the comercial
ones I posted?

Shouldn't Apache MINA or FtpServer be the right place for such a
development?

What do you think on those transfer protocols?

Thanks!

I'm not familiar with  these protocols, but I would say that some of
their claims are hard to believe... some of them they are 100x faster
than FTP while aspera claims that their fasp solution is 1000x faster!

Although I do believe that you can increase speed by using UDP instead
of TCP and an optimized mechanism for reception  acknowledgment,
packet retransmision and such, I would like to know what the real
figures are.  Have you checked any of these?
