FormsAuthentication.Encrypt produces a serialized
FormsAuthenticationTicket object...

Yes, but only on Windows. You'll have to define a COM or a DOTNET
object and decrypt the cookie the Windows way, using
FormsAuthentication.Decrypt...
A much simpler solution would be to tweak with the ASP.Net code and
have it explicitly set cookies based on FormsAuthenticationTicket
properties (CookiePath, Expiration, Expired, IsPersistent, IssueDate,
Name, UserData, Version). Something along these lines:
Dim cookie As HttpCookie
cookie = New HttpCookie("Expiration")
cookie.Value = authTicket.Expiration.ToString
Response.Cookies.Add(cookie)
Then, instead of dealing with the serialized object in
$_COOKIE["FormsAuth"], you would be dealing with plain and simple
$_COOKIE['Expiration'].
My guess is that about the only value you really need is Expiration...
