Bert, we had a conversation about database stuff a while back, and I recently ran across this again because I have a practice that wants their specialty lab to interface. Lab has an HL7 interface, but AC has to build the bridge in - 5K.
I brought this up at ACUC2010, and more than the money, the vibe I got is that the queue is pretty long - measured in months.
I've been doing XML since the early days, and my understanding is that the vast majority of the interface process is mapping and processing the XML encoded data.
Since it is piece work, I wonder if we can convince Jon to sub out the work, and just run the final acceptance-QA/QC in-house.
