It is a single international AwareIM application with 150 users using it as a calendering and coordinating operation. The forms will be most stable and require little modification after the first month of operation. This is a pro-bono endeavor that supports 150 volunteers in five countries who pay their own way.
A dedicated server is too expensive an option even at $60 (US) a month. I have previous international hosting experience where I was located in one country and the host in another. So, I do understand this option.
A shared server is preferable but most hosting providers contacted consider Tomcat too demanding. Having no track record on the number of starts and restarts, nor actual experience with AwareIM, it is difficult for me to lay out a standard hosting requirement.
A static IP situation I have also considered. For an international support system, however, I hesitate to go this route even with good UPS because of the demands of me and major thunderstorm history of our area.
Hence, my asking for any existing providers who have had experience with AwareIM. Thank you!
