Drupal Multisite, same module name, different site We have a module that needs to be the same name, but its functionality will change for each site.

Is it an ok practice to put put them in sites/site1/modules/MODULE_NAME and sites/site2/modules/MODULE_NAME

Will this cause any problems with drupal if they have the same name, but are in different sites?
As long as they are in the individual sites' directories, the are only visible to the sites they are associated with. Should be no problem.
