A couple of feature requests that would be helpful for the API Hit restrictions.
#1 Query Hits Remaining - It would be really useful if there was some method that would tell you the number of hits remaining and time until the next block.
#2 Daily Usage Limit - Having the max hits per hour is a problem if you have usage scenarios where the usage is bursty. Since many apps won't be used globally. We have a shortage of hits during US working hours and a surplus of hits outside those hours. Would be much more useful to have just a daily limit.
For Enhancement Requests, please post on Idea on community.progress.com/.../default.aspx
