Try the Linux AC3D download on your system.
There's no animation but AC3D does support some of the the file formats you mention including DAE and Ogre - see

For you, a personal license is probably the one to go for. Group licenses are for multiple users and are best for company use (e.g. where users may change or servers are used). You can use any license on a non-networked machine.
The license will be good forever as the software will not time out. New versions and updates are free for one year. After that you may wish to upgrade your license to use a later version (at a discount). We recommend you keep a copy of the download.
You can move to another machine. Perhaps consider the additional machine at the time of purchase since this will cover another computer.
Thanks for the bug reports - will get these looked into...
