Dear Bio-data Movers,

GridFTP with UDT, from the Globus project, speeds long distance
file transfer by 4 to 10 times over standard FTP. The commercial
Aspera UDP software that NCBI and EBI use may be better in
value, but is way out of my price range.

I've been testing GridFTP for use with Bio-mirror.net, to sites in
USA, and China Bio-mirror (hoping to add Australia, etc).
This looks like a good idea for biology data transfer. GridFTP is
well developed for a science informatics project. 

Here are some docs on this GridFTP server for Bio-mirror data
  http://gridftp.bio-mirror.net/biomirror/

This is early in testing stage. There are basic documents at this
web page, and I've more testing to do with it, but it seems to be
working well.   

If you may be interested in testing this, especially those outside
North America, please contact me or follow directions above and
let me know how it works for you.
