CoupleNewbie Questions

Im new to Zoho, been a Salesforce user for a LONG time.

A few questions before I dump alot of time into Zoho...

1. Can a page (code) from another server be displayed on the detail views of records?

2. Are there unique ids for all records useable for integration with other systems? What do these ids look like? I ask this becuase I do alot of work with image libraries on co-located servers integrating with Salesforce, I am hoping to do the same withZoho.The id fields are key to making this work... (ie: unique Account id string, uniqe id string for related records.

3. Can Templates be created from scratch and include related record lists/data? ie: production order forms, shipping labels, quotes etc... What formatcantempaltes be made in? html, xml, etc...?

4. Can databases be created from scratch with formulas, custom URL buttons, fields, layouts etc.?

Some of these answers maybe obvious, but Ioppologize I havent spent muchtime looking around yet.

Thanks for any input. Any Salesforce converts out there?
