If you and your kids each have different Windows user accounts, then that will do just fine. No need to make a 2nd Freelancer installation. If you or your kids want to use FL mods independently of each other, then you'd need different FL installations.

Online account Informations are kept in a part of the registry that is unique for each Windows user, however with admin right it is possible to manipulate those account informations, even if the user that these informations are from isn't logged in, so it would be best to make a backup of those, just to be on the safe side. To do that, click your way through "start -> run", enter "regedit", hit "F3" (search function) and type in "flaccountname". The first "flaccountname" it finds is the one for the Windows account you're currently logged in with. To make the backup, just click on "file" -> "export", then put the .reg file somewhere your kids can't find and / or change it. To restore the online account information, just do a doubleclick on the exported .reg file, then click "ok" to import it back into the registry.

If you look at that .reg file with a text editor of your choice, you'll see that it contains a bit more stuff than just "flaccountname". Thats ok. You could trim it down a bit thou, but that's not at all neccessary. Just make sure that if you delete something out of the .reg file, the following stuff stays in:
<pre><font size=1 face=Courier>Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Microsoft Games\Freelancer\1.0
"InstallKey"="some large, individual line of number & letters"
"MPAccountName"="some more large, individual line of number & letters"
"MPAccountNameSig"="even more large, individual line of number & letters" </font></pre>
