creating DICOMDIR diirectory to a USB memory stick?

I first saw your product last evening and have so far been impressed (you certainly can't beat the price!) We have been able to burn CD's but we also wondered about the possibility of having K-PACS create the DICOMDIR directory onto a USB memory stick or external USB drive rather than onto a CD. We also would be curious as to your plans if any for including a viewer on the CD and also password protecting the CD (similar to what Stentor and Efilm do). Keep up the good work

Do you have any estimate as to the timeframe for release of this functionality? We need to migrate the cd burning function to another box and we are not eager to send more money to the Efilm folks.
