I thought about it some more, and it might work like this: LocalAppBroker: Here is biodata in LocusML 3.5. I want to align these two nucleotide sequences. RemoteAppBroker: I have nucleotide sequence aligner 2.7. Let me check. Okay. That will require viewer 5.6. LocalAppBroker: I don't have that. Send it embedded in the LocusML. If the local app broker (or user's installation) does have the right viewer... LocalAppBroker: Here is biodata in LocusML 3.5. I want to align these two nucleotide sequences. RemoteAppBroker: I have nucleotide sequence aligner 2.7. Let me check. Okay. That will require viewer 5.6. LocalAppBroker: I have that. Send just the results of the analysis. Jeff -- J.W.
