What are the limitations of Cliq Network vs Cliq Local

What are the limitations of Cliq Network vs Cliq Local

I found that you get 5TB of space up to 10 users with Zoho One then it increases 500GB per user.  This seems to apply to the Cliq space when uploading photos/videos, etc. 

However what are the space limitations when using Cliq Network?

We have a web design company and want to setup external channels on a Cliq Network, one channel per client. That way the clients can upload the photos/videos they want to use on their site.  

I could do this with the regular Cliq and external users/channels but you're very limited to the number of external channels. 

Thanks!
