It could be worse.
The VC could have decided that you should use Oracle Application Server 10g.
And then let your customers freely decide what hardware and OS to purchase, to run it on.
And let the customer freely decide what network topology they want.
And then have the marketing guys decide what features you application should have.
And then have the fincancial controllers influence the purchase orders to fit their budgets.
And then have the business guys set your product launch date.
And when you to try to tell all these people about the mess they've
created and the technically impossibilities and project risks then you
are regarded as the negative guy.
And when you can't deliver on their promises the blame is entirely yours.
