Sorry to come into this thread late, but I just noticed your post starting this thread...
I am using Yardi Professional Property Management with the Custom Module for New York on 5-7 win clients+win2k server.
I am looking for exactly the same thing. I have come up with not very much.
As far as running Yardi through a program like Crossover Office, I have yet to try it, but given that the only persons I ever saw try that, ended up attempting to start the program with a bunch of switches and flags. See here: http://www.winehq.org/hypermail/wine...3/01/0981.html
and since Crossover Office uses wine, I would imagine that it would have the same output. They did find a solution though, which is nice to see.
there is also this choice: http://www.gnosio.com/
- they seem to be running an open source solution on a subsciption basis. who knows if its even maintained anymore.
I realize that wine is getting improved upon every day, but it is doubtful that it would useful in this capacity being that Yardi is accounting software mainly and the integrity of data (very valuable accounting data) is easily lost/corrupted even on it's native platform.
I think the best solution, unfortunately, for the property management company is to develop a web based app on their own, to suit their needs. Their costs to run it would be much lower if the platform didn't matter. A scalable solution to feed to whatever client OS they wanted to use. But that is not really very cost efficient in the end due to development costs.
for fear of going on way too long, I will stop there. I have researched some on the subject and would be glad to hear your thoughts.
