of using PC Anywhere Solution is that it installs the plugin-agent AND the quick connect 'client' on each PC. Most people I've worked with don't want the quick connect. So, a short answer is 'what you what to do is not currently possible'.
If you have a valid PC Anywhere serial number, you should be able to access the PC Anywhere software (not solution) via Symantec File Connect. This will include the PC Anywhere Access server, and other components for which you are licensed.
As you have surmised, if you use the stand alone software, it will not integrate with the Altiris based solution.
