No, Aware IM needs Tomcat - full stop. It cannot work with IIS, Apache or other web servers.
If you want to use Zoho editing you need Aware IM to be running on port 80. I don't see why you need other web servers but if you do then reconfigure them to use a different port. If you can't then you can't use Zoho editing. Use another server where you can run Aware IM on port 80.
The problem with "Form changed by another user" will be fixed in the next maintenance build.
