Bandwidth/governance limits in CRM Online?

One of our prospects asked the other day if Microsoft Dynamics CRM Online enforces a bandwidth/governance limit on calls through the API (apparently they had this problem with Salesforce.com). I did some research and ask the appropriate Microsoft people this question. They pointed me to the Microsoft Dynamics CRM Online Terms of Service which states there is no currently no limit (but Microsoft reserves the right to implement one):

10. Limits on Service

Microsoft may establish limits on the Service. For example, we may limit

· the number of days the service will retain any content that Microsoft, you or other users may post or provide,

· the number and size of e-mail messages that you may send or receive through the Service,

· the maximum storage space on Microsoft’s servers available to you,

· the number of users on your account or any associated accounts,

· the number of Service accounts to which you may subscribe,

· how long we retain an inactive Service account, which we define as one where you do not sign in to the Service for an extended period of time, and

· the number of transactions you can conduct through the service.

· the number of asynchronous transactions that can be executed with an organization

If you exceed the published Service storage limits, Microsoft may give you the right to delete data until the storage limit is met. If you exceed the published Service limits, Microsoft reserves the right to cancel your service.
