[Projects 2.0] :Love the Zoho Project one issues

Currently I use MS CRM 4.0, Sharepoints, & MS Projects! I like how I'm able to customize these systems. Send invitation with my own company branding. My question why do my client have to sign up for a personal Zoho account to access Zoho Project. Why can it be sign up based directly on Zoho Project .
