[BioC] Affy's .DTT format?

Hi everyone,

Our core facility was told by our Affy rep they should switch to the .DTT 
flat archive file instead of the CAB format as the way to store data and to 
disseminate it to researchers. However, this file format is basically 
useless right now without Affy's Data Transfer Tool and GCOS software; to 
get the .CEL files, I had to use the Data Transfer Tool to import the .DTT 
file into my local GCOS database, then use it again to export the flat .CEL 
files.  I've talked with our core, and instead they are going to give out 
the .CEL, .CHP and .DAT flat files, at least for now. I noticed that Affy 
does have a DTT SDK, and wondered if anyone within Bioconductor was 
planning on/working on being to import data from the .DTT format? I'm not 
sure what our rep was thinking, because I don't think any analysis software 
out there can take .DTT files (yet?).

Cheers,
Jenny
