Good news : all parts of Izotope RX2 (VSTs and DirectXs) are capable to recognize Vegas as a host properly.
But in this mode there is real problem with navigation in editor TL (editor as a plugin doesn't have his own TL navigation, and there is no synchro between Vegas TL and editor TL). You can use Izotope RX2 as event audio fx (new feature) and it captures sound properly. Izotope support will take it under scrutiny. Effect is, that you can't capture sound to spectral repair editor.
Under SVP10 we have problem with working as non_real_time effect (spectral repair is designed to work like this). I have tested Izotope under SVP10 and sent my tests to Izotope support, they confirmed. IMHO, they are worth the price if you do this as a business. Sorry if this sounds like an advertisement but I really like iZotope's products. I use it on almost all of my projects and it comes will a lot of presets for different situations so if you don't know what any of that stuff means, but you do know that you need to make the vocals sizzle, or the drums kick. It really adds a shine and polish to dull audio recorded in the field. If you haven't tried Ozone 4 on your mixes you are in for a treat.

Ozone is an audio mastering pluging for finishing your audio and you are correct that Ultimate S Pro ships with a special version of Ozone technology which includes three of the modules in Ozone 3 that is only accessible as presets from within Ultimate S Pro. but with RX, you actually can remove the dog barking and leave the person speaking!!! Like I said, it's voodoo. I call it voodoo because when someone would say, "can I erase a dog bark during an interview without affecting the voices?" we would say, "no, that's like trying to take the eggs out of a cake once it's baked!". It actually visualizes the audio and you can erase pars of the audio spectrum that you don't want while retaining others. RX/RX2 is an audio noise reduction program and plug-in that can DeClip, DeCrackle, DeNoise, and preform Spectral Repair on audio like you've never seen before. Is Rx and Ozone part of Ultimate S as well.
