What a pleasure it has been to read all of your DD--I am so glad that you are posting on this forum again. Avot tech seems like it will be great! I remember thinking that one of the benifits to Crossflo is that it can be tailored to fit the needs of the client. Now I am wondering if Avot could be used to benifit the Crossflow data sharing. If a barcode reader can be used I can see where it could be used in the pharmacutical and medical fields. Thank you for sharing your DD--also, thanks to Design Guy, emit, StormKing, and others. It was nice to log in and read the postings. GL, ads
