Very interesting. Thanks for sharing! Depending on how this is done, it can potentially disrupt on-demand cloud services, like AWS EC2/Lambda.  But there are problems that would have to be solved: 

1. Ensure strict isolation of DAPP containers - Access only specific local resources. Ensure someone cannot develop malicious DAPPS intended to harm/scam other people on the network. 

2. Setting caps/limits -  Allow network participants to statically or dynamically adjust how much of their resources they want utilized. 

3. Speed - Running  a function on the blockchain must be fast, very fast. Otherwise, the types of operations will be limited to things that are not time-sensitive. Like batch processing work. 

I'm sure there are much more problems than this, but just a few things that I can think of.
