Startup Idea: Cross-Platform Calendar Synchronization Tool

Startup idea to develop a software solution that enables easy scheduling of meetings, by automatically syncing and merging various calendars (like Google Calendar and Outlook) into one unified view. This would significantly simplify the process of checking the availability of coworkers and clients, in real time.

one of my problems at work is its really hard to schedule meetings with a large group of people. we use google calendar but the client uses outlook. to see if the client is available i have to go to the intranet computer and look them up manually and then compare it to the shared employee and cowokreer calendars i have on my work computer. i would like to be able to run amerge through a new system to sync the calendars and make sscheduling easy. this would help in consulting, accounting, and other contractor jobs!.
