Jamie, We are not claiming superiority, just that we provide performance gains over TCP when going over wan or congested networks. In-fact, we have a ftp server set up in Singapore if you would like to compare our technology to your ftp solution. you can find the client download on our

Hello Matt, * Matt McCutchen [EMAIL PROTECTED] [20070716 21:07]: I looked at the syncdat feature list ( http://www.dataexpedition.com/syncdat/features.html ). Aside from the claim of much better performance, syncdat appears to be equivalent to a combination of rsync, unison, and ssh. Mike,

2007-07-16 Thread Mike Jackson
Hello Matt, You are correct when you say that syncdat is a rsync or unison like product but what sets them apart is the enhanced performance over a wide area network that syncdat provides. By utilizing our MTP technology, sycndat is able to scan and send changed files up to ten times
