There are a couple of reasons why we don't see a lot of commercial companies switch to internet-based distributed computing:
1. Most of the moddeling that requires that amount of processing is likely to also have tons of data to be transferred. Most people's internet-connections are (currently) not useable for this amount of data.
2. Implementation engineering is costly.
3. Clusterfarms can have a lot of benefits for some tasks if used correctly, although they are costly at purchase.
4. Most uses for these kind of projects tend to be innovate research that companies are doing. They do not want their research studied and/of imitated by competitors.
Summary: It's not a profitable businessmodel (yet?), otherwise a lot of commercial companies would have already tried it.
